RAILWAY-TIE ?LATIE Application filed December 39, 1907. Serial NeJiGBfi i-Q.

Specification of Letters Patent.

Patented. March 2, 1909.

To all whom it may concern:

Be it known that 1, WILLIAM S. il usion, a citizen of the United States, and a resident of Chicago, county of Cook, and State of lllinois, have invented new and useful improve ments in Railway-Tic Plates, ofwhi'eh the iollowing 1s a lull, clear, and exact descr1pti'on.

My invention relates to improvements in.

railway tie plates of the class that are interposed between the base of the rail and the tie,.stringer, or other substructure on which the rail is thereby better held and supported; and has for its primary object the provision of new and improved means integral with the tie plate for preventing the longitudinal movement or creeping of the rail over the plate and substructure. The novel means for attaining this f nction in a tie plate, together with other novel features of improvement, are hereinafter described, clearly illustrated in the accompanying drawings which form a part of this specification, and particularly pointed out in the claims.

In the preferred form of my invention, and as illustrated, l accomplish my full purpose by means of a tie plate provided with an over-hanging resilient lip on one side ada ted to bear on and clamp one of the rail ase flanges, and, on the other side, with a serrated or roughened shoulder adapted to bear against the. edge of the other rail base flange. The tie plate also preferably has a downwardly rejecting lug adapted to engage the tie orsu structure.

In the drawings, Figure 1 is a plan view of my invention in position of service; Fig. 2 is ;a vertical cross section of the tie plate and rail on the line 2-2 of Fig. l Fig. 3 is across section of the rail and plate showing how the plate is put; in position; Fig. 4 is an edge view of t is plate with a dotted outline of the rail to show the relative shape of the overhanging lip when not in position on the rail; Fig. 5 is an enlarged scale plan of one corner of the plate, showing more perfectly the serrated shoulder; Fig. 6 is a partial sectional elevation onthe lines 66' of Figs. land 5; Fig. 7 is a section on the line '1 of-Fig. 5.

Similar letters refer to similar parts in the several views. Referring to Figs. 1 and 2, A is the tie plate, T the tie or substructure, and R the rail.

The tie plate A is provided upon its upper "face. with two integral ahutments B and l),

which are arranged to receive and grip the base of the rail between them. In the particular form of the invention illustrated, the abutment B is in the form of an overhanging lip or leaf integral with the plate and forming a recess C in which one flange of the rail base is placed. The abutment D is in the form of a shoulder formed upon-the upper surface of the tie plate and is arranged to engage the other flange of the rail base. The shoulder D is provided with teeth or projections E adapted to indent the fiange when the mills in position.

A lug or rih F dependent fronithe under side of the plate, Figs. 2, 3 and 4, adapted to be' embedded in the tie when in position. The rail is held down to the tie or substructure by means of spikes S, S. In the construction shown, the spikes are driven through holes S in the plate, the spike onthe side of the shoulder D taking effect directly on the rail while the spikes on the side of the li B take effect indirectly by holding the. plaitedown, the lip B being depended upon to hold down that side of the rail lease.

To get the best results with my invention,

the plate should be made from a resilient metal, suchas spring steel, with the jaw slightly closed up when in the free'position, as shown in Fig.

' To set the plate, it is first'siipped on the .hase of the rail to a position ap roximating that shown in Fig. 3, when itis rivento p osition by. striking on the edge H, causing the lip B. to spring up as indicated in Hi5 3, ask:

until the shoulder D clears-the opposite flange. The lip then recovers apart of its distortion and the plate takes a position approximating that shown in Fig. 2, with the edge of the base flange bearin against :the teeth E. E. The first load on t e rail, or the driving of the spikes, then brings it down to a full seat on the plate and causes the teeth to become wholly or partly embedded in the edge of the flange. It should he noted that;

"space is made'to allow fora variation in the width of rail bases of nominallythe same section. In some instances; the width. of the space may he greater than the depth of the teeth la. in, end in case the plate is driven on hard enough to bring the Henge to the bottom. of the ZLW, the opposite iieiige will clear the teeth. For such cases the reaction. of the resilient lip B on the sloping upper surface of the base flange is depended upon to restore and maintain contact against the teeth, while the wearing so tion between the rail and the plate, due to taking the load on end oil? the rail, is depended upon to cause the teeth to become more or less indented in the rail.

As stated at the beginning of these specifics-- tions, the primary object of my invention is to provide a, tie plate which will prevent longitudinal movement or creeping of the rail over the substructure. ln the best socornplishment of this object with the tie )lete illustrated and described, the resilient lip B and the serrated or tooth shoulder D grip the rail base to prevent movement of the rail over the plate, while the dependent lug F and. spikes S engage the tie to prevent movement of the plate over the tie.

While the combination or the four elements, the resilient lip B, the serritted shoulder D, the dependent lug F, and. the spikes S, gives the greatest power for holding the rail, yet I do not wish. to limit mysell to this exact combination. It is unnecessary that the grip between the rail and the tie should be positive. In fact it is prelerzthle that the grip yield before the tie be ins to move on the ellcst or other substructure on which is bedded. l may, therelore, by the use of it greater numberoi tie pistes, depend. upon the friction contact oil the ew C on the rail to hold it from. creeping, end dispense Withthe teeth E. E. Or the lip l3 iormmg the jaw C might be much smaller, that is, merely a shoulder having little or no iric tionsl grip on the rail, in which case .1 would depend upon the indentation. of the teeth E in the edge of the rail "When spikes are driven through holes in the tie piste shown, I mey dispense with the lug c and depend. upon. the spikes :Sor holding the plate against transverse. movement on the tie. G11 the 0 hand, by the use of the lug l. l: m "-v dispense with the s, so fer us the functions of my invention are con-- corned.

a used to h .o the urse moi omen end me pieced. hy other hold lg the raid, end. yet, .-.1y device iul its purpose of s P the rail longitudinal nu An important a vention also con provided for holding t thrust of the iced, or-eg the rail to buckle under i sure This purpose is combination r. l WlllL evel. lecture my the im uesios .guinst the side it u. tendency cl inlinel mes move in any transverse direction Without telling the plete with it, and thereby bringing into eil'ect the full. holding power of all the spikes pit. 4i through the plate.

Another feature cl novelty consists in the 7 O combination of e tie plate and en unttcreepiug devicein oneintegral piece. By this few ture i sin enabled to reduce the number of per-ts to he used in track equipment and thereby accomplish at saving in primary and maintenance cost.

Attention is called particularly to Figs. 2, 3 and 4: to note that the device is a single piece clamp which does not require the use of e separate spike, belt or key. 'Vl hen sprung into the position shown in Fig. 2, the seating of the rail relative to the pl ate is maintained by the weight of the roil or by the resilient action of the lip P and the clamping effect is accomplished independent of the spike S on the left of Fig.

it should be noted that the improved de-- vice constitutes combined tie plate and ole-mp, end that the lips B and shoulder 1) thereof constitute ebutments between. which the rail base is gripped. In the particular form of the invention illustrated, the resilient lip ll is shaped that the space bounded by it and. the shoulder D issmsller than the rail base, as indicated in full lines in Fig. l. The rail hese, however, can be niiechenieelly forced into position bet. *cen the shoulder and the lip, since the latter is resilient end is dis torted to enlarge or expand the space which receives the rsil. The resilientoortion 106 or will then tend to react and wi l force the mil against the shoulder D, as described, so that the rail base will be securely gripped between the oh'utments of the enti-creeping clamp ortie plate. llloreoveiyeven-if thebuses 05 of the rails very slightly in size, as is sometimes the cuss, they will be securely gri ped, since the lip or portion E is surllcient y resilient to tslre core of any such variation. While the invention is preferably in the form 0 of a tie plate, as set forth, it comprises broadly an anti-creeping device or clamp for reilwoy rsils heving 'cbutments for gripping the opposite edges of the rsil base and torming s centre A some sil htly smaller then the ion e the device being u new and desire to secure by Letters i l 0 device tor reilvmy mils .tel end halving integral to; term contracted 13G in utinests one described my invention what I 1% space slightly smaller than the rail base, a
